Here, diamond drilling campaigns have been carried out, as well as the respective sampling, in order to obtain information on the presence of economic minerals in the deposit (gold, silver, and copper).Its geology corresponds to volcanic rocks cut by subvolcanic bodies and hydrothermal breccias. In addition, it has a lithological model that differentiates pyroclastic rocks from hydrothermal breccias. Some of the alterations contained include: mass silica, leached silica, advanced argillic, argillic and propylitic, common in a high sulfidation deposit. Concerning mineralization, gold is present in submicroscopic particles related to iron oxides; silver and copper values are minimal.
